Answer:

The correct answer is c.With an RNA virus, radioactive RNA would have been in the final pellet.

Blababa [14]

Answer:

For the photossynthesis there are requirement of cholorplast which is found on the surface of the plant leaves mostly that traps the light and convert light energy to the storage energy or glucose. Leave have larger surface area so the maximum amount of light can be traped for the photosyntheis by the cholorplast present in palisade cells.

Other than this leaves also helps in the gaseous exchange with stomata; small openings, by allowing carbon dioxide and oxygen into the leafe and outof the leave respectively. The veins helps in the transport of the gluscose and nutrition.
